BRACE FOR CARRIAGE-SPRINGS.

Specification of Letters Patent No. {5,914, dated October 14, 1856.

To all whom it may concern: r

Be it known that I, THOMAS DUTTON, of \Vashington City, in the District of Columbia, have invented a new and useful Mode of Holding Carriage and other Springs in Place while in Motion; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

Figure 1, is a perspective view of the brace as attached to a vehicle with a perch. Fig. 2, side elevation of the same. Fig. 3, perspective of the brace as attached to, carriages without perches. Fig. l, view of a cam to be used in place of the bent lever b when desired.

The same letters refer to the same parts in the difierent figures.

The nature of my invention consists of a combined brace and lever which are selfregulating; said lever being composed of a toggle-joint, one leg of which extends past the fulcrum (a which is attached to the spring as shown in Figs. 1 and 2 and attached to the axle as in Fig. 3, so forming a lever (22) to which a brace rod (6) is made fast by a joint, while the other end of the said brace rod is made fast by a similar joint at any required place on the perch of the vehicle (as shown in Figs. 1 and 2) or to the ends of the fetches or hounds when perches are not used (as shown in Fig. 3).

It will be seen that when the spring is open, the brace rod, with the perch of the carriage and the toggle-joint and lever, forms, as it were, a right angled triangle, the brace rod being the hypotenuse and that as the spring closes the lever extending from the toggle joint takes up the excess of the hypotenuse.

In making this brace the point of the lever marked (6) may be constructed with a slotfor convenience in adjusting the brace rod, as may also the fastening upon the perch (or other point of the vehicle) for the purpose of taking up the wear of the joints.

I do not confine myself to the precise form above described but alter it according to circumstances; for instance, when a carriage is so hung as to leave no room for the leg of the toggle to extend past the fulcrum, I reverse the toggle, throwing the knuckle forward or in an opposite direction to the point of fastening the brace rod and connect the brace rod to the toggle at any desired point on the arm or leg of the toggleiwithin the fulcrum and thereby obtain the compensating motion as the spring closes.

What I claim as my invention and desire to secure by Letters Patent is The combination of the brace rod with the toggle joint and lever or any of their equivalents, substantially in the manner and for the purpose herein set forth.

THOS. BUTTON.
